System-specific DDR3 SO-DIMM kit

This 8GB kit contains two 4GB DDR3 1066MHz SO-DIMM modules built for the Asrock CoreHT 231B and Vision 3D 156B mini PCs. It uses 204-pin unbuffered non-ECC memory running at 1.5V with CL7 timings. The kit matches the exact specification those systems require.

Straightforward slot installation

Each module inserts vertically into the SO-DIMM sockets until the side clips lock. The low-profile design has no heat spreader, so clearance inside the compact chassis is not an issue. Problems only appear if the slots are dusty or if a module is not fully seated before the clips engage.

Steady throughput for everyday workloads

At DDR3 1066 (PC3 8500) with 7-7-7 timings the memory delivers consistent bandwidth during extended office, media or light multitasking sessions. The unbuffered 2Rx8 organisation keeps latency stable without the variability seen in registered designs. It is not intended for workloads that need ECC error correction or higher frequencies.

Questions about this item

How can I verify the kit is running at 1066 MHz with CL7 timings after installation?

Open Task Manager or a tool like CPU-Z and check that the memory frequency shows 1066 MHz (PC3-8500) with timings of 7-7-7 at 1.5V.

What comes in the box and do I need anything else for the CoreHT 231B or Vision 3D 156B?

The package contains two 4 GB DDR3 SO-DIMM sticks (model CM512648500SODRH). No extra parts are required for the listed ASRock Mini PCs.

Which capacity should I choose if the Mini PC supports a maximum of 8 GB across two sockets?

This 8 GB kit (2 x 4 GB) fills both sockets and matches the system's 8 GB maximum, so no other capacity is needed.
